T 0 all whom it may concern.

Be it known that I, ERRETT E. PHILLIPS, a citizen of the United States,residing at New Castle, in the county of Lawrence and State ofPennsylvania, have invented certain new and useful Improvements inExcavating Apparatus; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in hoisting andexcavating apparatus for use upon the surface of the ground orunderneath same for various purposes, where soil and various materialsare desired to be excavated, hoisted and dumped.

My invention consists of a simple and efficient device of this characterhaving various details of constructions, combination and arrangement ofpartswhich will be hereinafter fully described, shown in theaccompanying drawings and then specifically defined in the appendedclaims.

My invention is illustrated in the accompanying drawings which, withtheletters of reference marked thereon, form a part of this application,and in which:

Fig. 8 is a detail view of means for bold ing the boom, illustrated inFig. 1, in (hit ferent adjusted positions.

Reference'now being had to the details of the drawings bynumeralsz' IReferring to Fig. 1 of the drawings, .1 designates the base upon which asuitable derrlck 2 is mounted, havingcrossbeams '3 at the upperendthereof, in which are ournaled pulleys 4 and 5. A pulley6 isjournaled in suitable bearings upon a cross piece 7 of the derrick, and8 designates an other pulley which is journaled insuitable bearings nearthe lower part of thederrick.

A swinging boom, having parallel pieces, has a bracket shaped member 9connecting their inner ends, and which member is pivotally connected at10 to a yoke 11, havin apertures toreceive the vertically dispose rod 12which is fixed to the derrick spaced apart a slight distance therefrom,asshown passes over the pulleys 4,4 and 5 under neath the pulleys 8 andthence extends to and passes about a reel 26 journaled upon the capstanshaft 27', which has a squared end 27 adapted to receive the capstanlever 31provided with a similarly outlined opening therein to receivethe angular outlined part of the capstan shaft 27'. Integrallugs 28project from the upper face ofthe reel, and are provided withregistering apertures to receive the rod 30 asshown clearly in Fig. 3 ofthe drawings, which rod also passes through a registering aperture inthe capstan. A rope 1 1 is fastened at 14 to the yoke 11 and passes overthe pulley 6, and carries at its, other end a handle piece 14,

which afiords means for raising and lower- A handle 1 is fastened to thebracket member and serves as a means for swinging the latter to engagethe spaces intermediate the lugs or to be drawn free from the same topermit the boom to be raised and lowered while in operation.

In Fig. 8 of the drawings is shown additional means for holding the boomin different adjusted positions, and consisting of yokes having integralcollars 86 at the ends thereof, adapted to receive the vertical rod 12rising from the sill of the derrick, and which yoke has a handle 37fixed thereto, providing a convenient means for swinging the yoke, sothat the projecting members 38 thereof may be made to engage therecesses 39 in the post 40 of the derrick.

A scoop shovel, Fig. 4, 1'7, with a suitable handle 17, has straps 18fastened thereto, each of which is supported by rings 19, adapted toreceive the rod 16 upon which they are movable. Said scoop shovel has arear end 20 which is hin ed at 21, and is provided with a latch 22, and23 is a rope fastened to said latch and forms means for releasing thesame when it is desired to dump below it.

In Fig. 5, I have shown my invention illustrating a vertical hoistingcage 40, which has guide wheels 41 hearing against vertically disposedparallel tracks 42, said Fig. 5 illustrating a car 48 mounted uponwheels, this car is within the cage 40. A hoisting cable 44 is securedto ring bolt 45 upon the cage, passes over a pulley 46 rotating on topof the shaft 47, which latter also carries a pulley 4S. Said cable 44passes underneath a pulley 49, and thence extends to and passes about awinding reel 50, which is of similar construction to the reel beforedescribed, and illustrated in detail. in Fig. 3 of the drawings, saidreel having, however, a slightly modified form of means for causing thereel and capstan to rotate together, which consists of a sliding anglerod 51 held in suitable eyes 52, and adapted to engage apertures 53 uponthe reel, said eyes 52 pro jecting from the lever 54.

Upon reference to Fig. 6 of the drawings, it will be noted that the rope44 passes over a roller 55 which has a vertical movement, detail ofwhich is shown in Fig. 7 of the drawings. Said roller 55 is mounted upona bar 56, and 57 is a lever fulcrumed upon a pin 58 upon the standard 59and which is connected to the bar,andby pressure on the lever, the barcarrying the roller may be raised to the position shown in dotted linesin Fig. 7 of the drawings. Asa means for holding the bar carrying theroller in different adjusted positions, abracket rod 60 is shown ashaving angled ends adapted to engage apertures in the standards 61. Thecapstan shaft, it will be noted upon reference to Fig. 5 of thedrawings, is supported by bars, these laid in concrete for foundation.For purpose of guarding the entrance to the elevator shaft at thesurface of the ground, a'suitable screen 42 is placed upon the shaft.

A suitable counter balance weight 62, shown in Fig. 5, has a rope 63fastened thereto which passes over pulleys 64, and thence about thepulleys 48, in order to hold the cage in elevated'positions. Ring bolts,one desi nated by numeral 65 and fastened to a ross beam 66 of the shaftin which the cage is mounted, and the other,.67, on the cage, and 6Sdesignates a double ended snap hook designed to engage the two ringbolts when the cage is elevated.

in the modified form of means for holding the cage elevated, consistingof a chain 70 passing through rings, as shown in Fig. 5 of the drawings,and a padlock '71 nay be passed through the rings at the end of thechain to hold same iocked. An additional means for supporting the cageconsists of a horizontally movable rack bar 72 havin teeth upon theunder surface thereof, and designed to be engaged by theteeth of thegear wheels 73, one of said wheels being rotated'by means of a crankhandle secured thereto, so that when the cage is elevated, the rack barmay be moved underneath the same by rotating one of the gear wheels.

In operation, through the medium of the hoistin cable 13, the boom 9 maybe held to operate at different elevations. By rotating the capstan 11the reel will cause the cable 13 to wind thereon and the scoop shovelmay be drawn through the soil or other material, the scoop shovel beingdirected through the medium of the handle 17', and when the scoopshovelis loaded and further pulling applied to the hoisting cable 13,the boom 9 may be elevatedjto any desired position and may be swung indifferent directions laterally, and when it is desired to dump the load,it may be done by the operator pulling upon the rope releasing the latchupon the scoop shovel, permitting the materiai to fall out at the rearend thereof.

When it is desiredto pullback thescoop shovel to its original startingposition, the rod 30 may be withdrawn from engagement with registeringapertures in the lugs upon the reel and capstan, and the scoop shovelmay be pulled back through the medium of the rope 23 secured thereto.The boom, it will be noted, may beheld in different positions throughthe various means illustrated in Fig. 2 of the drawings, or throughthemedium of the mechanism shown in Fig. 8. The cable, as it winds upon thereel, may be raised through the medium of the lever 57 in order topermit the cable to wind evenly upon the reel. It will be noted that themeans for causing the reel and the capstan to wind together is ofsimilar construction, shown in Figs. 1 and 5 of the drawings, the cagein Fig. 5 being permitted to be lowered by releasing the angled rodconnecting the reel to the capstan.

By the provision of a hoisting apparatus made in accordance with myinvention, it will be noted that a simple and efiicient mechanism isprovided for use either upon the surface of the ground or underneath asmay be desired, and while I have shown a particular detailedconstruction of applying the principle involved in my invention, it willbe understood that the detailed construction may be varied in differentways without in any way departing from the spirit of the invention.

What I claim to be new is:

1. An apparatus for hoisting booms, comprising a derrick, a verticalguide rod car ried by and spaced slightly from the derrick, a yokeprovided with apertures through which said guide rod passes, a swingingboom pivoted to said yoke, a bracket member having parallel angledportions apertured to receive said guide rod, the ends of said yoke andsaid angled portions being superposed, laterally extending arms carriedby said bracket member, and a series of spaced lugs carried by saidderrick between pairs of which said arms are adapted to be moved to holdsaid boom in vertically adjusted position on said guide rod.

2. An apparatus for hoisting booms, comprising a derrick, a verticalguide rod carried by and spaced slightly from the derrick, a yokeprovided with apertures through which said guide rod passes, a swingingboom pivoted to said yoke, a bracket member having parallel angledportions apertured to receive said guide rod, the ends of said yoke andsaid angled portions being superposed, laterally extending arms carriedby said bracket member, a series of spaced lugs carried by said derrickbetween pairs of which said arms are adapted to be moved to hold saidboom in vertically adjusted position on said guide rod, and a handlecarried by said bracket member by which the latter may be horizontallyswung so as to cause said arms to move between pairs of said lugs.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
